Answer 1

$4 sqrt{2 } + sqrt{5 times 5 times 2} - sqrt{3 times 3 times 2} = 4 sqrt{2} + 5 sqrt{2} - 3 sqrt{2} = sqrt{2} (4 + 5 - 3) = 6 sqrt{2}$
$3 + sqrt{12 times 3} = 3 + sqrt{3 times 4 times 3} = 3 + 3 times 2 = 9$
$3 - 4 sqrt{3} + 4 = 7 - 4 sqrt{3}$
$7 + sqrt{7} times sqrt{2} - sqrt{2} times sqrt{7} - 2 = 5$
